Formula
Each dimension grows by twice the bleed, because there are two edges:
sheet = trim + bleed × 2
An eighth of an inch, 0.125, is a common inch bleed. Three millimeters is a common metric bleed. Enter whichever unit you are already using.
Assumptions
- The same bleed is used on every edge.
- Trim width and height use the unit you select.
- Crop marks and a slug area are not included.
Worked example
An 8.5 by 11 inch page with 0.125 inch of bleed on each edge becomes 8.75 × 11.25 in.
Input definitions
- Trim
- The finished page after it is cut.
- Bleed
- How far artwork extends past one edge. It is applied to both edges of each side.
Limitations
Printers can ask for a different bleed. This page does not place crop marks or check a safe margin inside the trim.
Questions
Why does 0.125 become 0.25 on the width?
The bleed is added to the left edge and the right edge. The width grows by 0.25 inch, and the height grows by 0.25 inch as well.
Can the bleed be zero?
Yes. The sheet size is then the trim size.
